Mathematical Calibration of a Whole-Body Counter
This paper describes the mathematical efficiency calibration of the whole-body counter at Forschungszentrum Jülich using Monte Carlo codes and mathematical anthropomorphic phantoms. As a prerequisite for the Monte Carlo simulations a precise model of the 4 high-purity germanium (HPGe) detectors had to be developed. Because the technical data provided by the manufacturer were not sufficient for ...
متن کاملIndividual Calibration of Whole-body and Partial-body Counters by Means of Voxel Phantoms
accuracy of activity determination by means of whole-body and partial-body counters is no longer determined by errors in counting statistics, but by the bias caused by calibration. This is true in particular of low-energy photon emitters, such as Pb-210, U-235, Th-234 (daughter product of U-238), and Am-241. In addition, these nuclides in general show a very inhomogeneous distribution in the bo...
متن کاملEvaluation of Counting Efficiency of Whole–body Counter using Voxel Phantoms
The calibration methods for in vivo measurement systems using Monte Carlo simulations and voxel phantoms have been demonstrated. The calibration data, such as counting efficiency or response function, calculated by the UCWBC code that was developed in the Japan Atomic Energy Research Institute were compared with those measured with an in vivo measurement system. It was found that the calibratio...
